If true, it is pretty unprofessional workplace behaviour coming from two experienced and highly respected police officers. The main thing is that NSWPOL have found a solution in conflict resolution.
Pretty unprofessional behaviour from their colleague(s) who went to MSM too, rather than dealing with the incident in-house. (There are Employee Assistance Programs available to every NSW Government Department employee, staffed by psychologists, who can assist with counselling for people who witness incidents such as these.)
In saying that, like you, I can understand that tempers can fray in high pressure workplace situations. We’re all only human after all, no matter what our profession.
